1978年7至8月,对我盟北部两个牧区社队291头牛的牛乳及分泌物进行了抗酸菌检查,兹将结果报告如下: 材料及方法 1.取鲜牛乳10ml置于100ml三角烧瓶内,加入1ml二甲苯,用玻璃纸将瓶口塞紧盖严,振荡摇匀10分钟。 2.加入2～3％盐水至瓶颈处。(加盐水可提高液体比重,使抗酸菌易上浮) In July-August 1978, 291 cattle of two pastoral communes in the northern part of our Union were tested for acid-fastness against the bacteria and secretions. The results are reported as follows: Materials and Methods 1. Fresh milk 10ml was placed in a 100ml triangle Add 1ml of xylene to the flask, tightly cap the bottle with cellophane, and shake well for 10 minutes. 2. Add 2 ~ 3% brine to the bottleneck. (Plus brine can increase the proportion of liquid, acid-fast bacteria easy to float)
